Which of the following statements is always TRUE for the freezing of water?
Rom4ik [11]

ΔG > 0 is always true for the freezing of water.

Explanation:

  • The freezing of water is only spontaneous when the temperature is fairly small. Over 273 K, the higher value of TΔS causes the sign of ΔG to be positive, and there is no freezing point.
  • The entropy decreases as water freezes. This does not infringe the Thermodynamics second law. The second law doesn't suggest entropy will never diminish anywhere.
  • Entropy will decline elsewhere, provided it increases by at least as much elsewhere.

If 16.8 mL of the analyte H2C2O4 (oxalic acid) is titrated with 0.501 M KOH to 13.54 mL, determine the mass of the analyte.​
Neko [114]

Answer:

Mass of Analyte H2C2O4 = 18.18 grams

Explanation:

The balanced equation is:

H_{2}C_{2}O_{4}+2KOH\rightarrow K_{2}C_{2})_{4}+H_{2}O

The Molarity of Oxalic acid needed can be determined using:M_{1}V_{1}=M_{2}V_{2}

Here M1 = Molarity of Oxalic acid

V1 = Volume of oxalic acid

M2 = Molarity of KOH and V2 = Volume of KOH

M1 = ? , V1 = 16.8 mL , M2 = 0.501 M   ,  V2 = 13.54 mL

Put the values and solve for M2,

M_{1}V_{1}=M_{2}V_{2}

2\times M_{1}(16.8)=0.501\times 13.54

We are multiplying by 2 because , 1 H2C2O4 needs 2 KOH

M_{1}=\frac{0.501\times 13.54}{2\times 16.8}

M_{1}=0.202M

Hence Molarity of H2C2O4 =

0.202 M

Molar mass = H2C2O4 = 2x1 +2x12 + 4x16

= 2+24+64 =  90 gram

Mole =molarity\times Molar\ mass

Moles=0.202\times 90

18.18 gram
